.htaccess 301 redirect only work for 1 new link

I have .htaccess file with redirect 301 on it and placed right under the rewriteengine

<IfModule mod_rewrite.c>
RewriteEngine On
#now this is the redirect
Redirect 301 /blog.php?slug=konsolidasi-tanah-frequently-asked-questions https://jpi.or.id/blog/2021/02/11/pengertian-konsolidasi-tanah

Redirect 301 /blog/2021/02/11/konsolidasi-tanah-frequently-asked-questions https://jpi.or.id/blog/2021/02/11/pengertian-konsolidasi-tanah

</IfModule>

only 2nd redirect works, the one with the get method are not redirected, am i doing wrong?

EDITED :

this is my entire mod rewrite :

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.*)$ $1.php
RewriteRule ^index\.php$ / [R=301,L]
RewriteRule ^(.*)/index\.php$ /$1/ [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]
# Permanent URL redirect
Redirect 301 /blog.php?slug=konsolidasi-tanah-frequently-asked-questions https://jpi.or.id/blog/2021/02/11/pengertian-konsolidasi-tanah
# Permanent URL redirect
Redirect 301 /blog/2021/02/11/konsolidasi-tanah-frequently-asked-questions https://jpi.or.id/blog/2021/02/11/pengertian-konsolidasi-tanah

Redirect 301 /blog.php?slug=konsolidasi-tanah-frequently-asked-questions /blog/2021/02/11/pengertian-konsolidasi-tanah
RewriteRule ^blog/2021/02/11/pengertian-konsolidasi-tanah   /blog.php?slug=konsolidasi-tanah-frequently-asked-questions

It is usually not a good idea to mix RewriteRule and Redirect 301 directives. They can conflict with each other in unexpected ways. You depend of RewriteRule so you should implement your redirects with more of them.

Redirect 301 can't redirect based on query strings (?...) in the URL, so you need to implement RewriteRules for that redirect anyway.

When you have rules for redirecting specific URLs, they should go at the top of the .htaccess file so that they take precedence over the other more general rules.

I would recommend disabling the directory index because I fear it would conflict with your RewriteRule ^index\.php$ / [R=301,L] rule.

I don't see RewriteEngine On in your .htaccess file, despite that your snippet you posted to start with has it.

Try this as your .htaccess:

# Disable index.html, index.php default functionality
DirectoryIndex disabled

RewriteEngine On

# Permanent URL redirect
RewriteCond %{QUERY_STRING} ^slug=konsolidasi-tanah-frequently-asked-questions$
RewriteRule ^blog\.php$ https://jpi.or.id/blog/2021/02/11/pengertian-konsolidasi-tanah [R=301,L]

RewriteRule ^blog/2021/02/11/konsolidasi-tanah-frequently-asked-questions$ https://jpi.or.id/blog/2021/02/11/pengertian-konsolidasi-tanah  [R=301,L]

# Forward URLs without .php extension to existing PHP file
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.*)$ $1.php

# Redirect index.php URLs to the directory
RewriteRule ^index\.php$ / [R=301,L]
RewriteRule ^(.*)/index\.php$ /$1/ [R=301,L]

# Use index.php as a front controller
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]
